To all whomit may concern.

Be it known that 1, Jesse A. B. SMITH, a citizen of the United States, residing in Brooklyn borough, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

This invention relates to attachments for typewriting machines, particularly adapted to facilitate the rapid and accurate placing of work-sheets on the machine in position to be written upon. The attachment may be in the form of a paper table and guide adapted to be placed over the usual paper shelf at the intake side of the platen, the attachment extending forwardly beneath the platen and spaced therefrom to permit worksheets placed upon said guide to he slipped forward around the platen to writing position.

The attachment may comprise side flanges forming gages for the side edges of the work-pieces, said flanges having curved extensions beneath the platen of sufficient depth to properly space the guide from the platen. Arms which may be either rigidly secured to or hinged to said side flanges, may extend over the platen and around to meet the paper shelf beneath the platen, said arms serving to position and support the attachment on the platen, and also guide the work-sheets over the printing line. By hinging said arms, they may belifted to permit the attachment to be quickly removed from the machine without removing the platen.

The attachment may be adjustably secured to a rod behind the paper shelf and extending longitudinally of the platen, the attachment having a slidable connection with said rod whereby it may be adjusted to any position along the platen. The worksheet, when in position, may be held to the platen and fed forward by means of feed rolls, which may be thrown oif the platen to permit the work-sheet to be positioned.

Other features and advantages will hereinafter appear.

platen being in this case rigid with the attachment. F ig.'3 is a perspective view of one of the hinged guide arms shown in Fig. 1. Fig. 4 is a sectional elevation'view showing the parts in normal position. i Fig, 5is a view showing the method of removing the attachment from'the machine, the attachment being disconnected and thrown forward.

A rotary platen 1 is fixed to an axle 2, journaled in a platen frame 3. Type-bars 4 carrying upper and lower case types 5, may be operated in the usual manner to throw them upwardly and rearwardly against the front face of the platen for printing on the work-sheet. The platen frame may comprise the usual inclined paper shelf 6 at the rear of the platen, said shelf'connecting the ends of the platen.

The attachment embodied in the present invention comprises an inclined table 7 placed over the shelf 6, the lower end of said table being curved to extend forward beneath the platen concentrically with the platen. Side flanges 8 on said table serve as gages for the lateral edges of the worksheets. and the lower portions 9 of said gages Patented Sept. 7, 1915.

are reduced in width and curved to conform to the surface ofthe platen. the width of the extensions 9 being ust sufficient to hold the curved portion of the table 7 a short distance from the platen, leaving a narrow passageway 10 through which a work-sheet placed on the table 7 may be slipped forward into position to be written upon. Lateral guide arms 11 connected by pivots 12 to the flanges 8 extend forwardly over the platen and curve downwardly to meet the extensions 13 at the forward end of thetable 7. The attachment thus completely surrounds the platen. The arms 11 may have inwardly extended flanges or projections 14 which serve to guide the work-sheet over the front face of the platen and direct it backwardly over the platen. Said arms 11 serve to guide the sheet laterally until the final line is written thereon. The arms 11 further serve to hold the attachment accurately positioned with respect to the platen.

The upper end of the table 7 may be bent to a horizontal position, and rest upon the head or rolled end 15 of the shelf 6, and is secured by thumb screws 16 to brackets 17 slidably mounted for longitudinal adjustment on a horizontal rod 18 located behind of the platen frame.

the shelf 6 and secured to the platen frame in any suitable manner, as, for example, by arms 19 attached to the rear face of the shelf 6. The brackets 17 may be frictionally held in adjusted position on the rod 18 by leaf springs 20, which bear against pins 21 carried by the brackets and seated in a groove 22 extending along the upper surface of the rod 18. Thus the entire attachment may be adjusted along the platen, and the guides 9 and 11 may clasp the platen closely so as to prevent sheets from slipping between said guides and the platen.

The attachment may be removed from the machine by loosening the thumb screws 16 and swinging the arms ll-rearwardly about their pivots l2, and then swinging the attachment forward to the Fig. 5 position, when it is free to be lifted from the machine.

The guide arms 11 may be held in normal position by springs 23, each attached at its upper end to a pin 24 on the arm 11, and at its lower end to a pin 25 on the flange 8, the pin 25 also serving as a stop for said arm. The springs 23 also serve to hold the arms 11 when thrown back to the Fig. 5 position, the movement of said arms about their pivots being limited in such direction by a stop pin 26. I

In the modified form shown in Fig. 2, the arms 11 are integral with or rigidly connected at 27 to the flanges 8. When a bill or other work-sheet has been placed on the table 7 and slipped forward between the platen-and the table 7 to printing position, it is held in such position and fed forwardly over the platen by feed rolls 28, which may be located just forward of the front edge of the table 7. These rolls are mounted on a shaft 29 as supported in levers 30 journaled on a tie-rod 31 extending between the ends The rolls are lifted from the platen by means of a finger-key 32 connected through a link 33 to an arm 34: on a rock shaft 35 provided with flats 36 in engagement with arms 37 of the levers 30. .When the finger-key 32 is depressed,

the shaft 35 is rocked and lifts the feed rolls 28 from the platen, permitting a workpiece to be placed on the platen or removed independently of the rotation of the platen. When the finger-key 32 is again lifted, the rolls 28 are returned to the platen.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I
